Standoff Insulators are designed from a fiberglass-reinforced
thermo-set polyester, which is a bonded material that offers a
higher moisture and heat tolerance compared to that of plastic
insulators.
Additionally, standoffs offer excellent mechanical strength for
allowing electrical installers to raise close height tolerances
compared to that of porcelain insulators. They are flame retardant
and offer high arc resistance, track resistance, and shatter
resistance as well.
